What are the key features of SFM-109-02-LM-D-LC-TR?
- 18-position dual-row (2 x 9) layout at 0.050" (1.27 mm) pitch for space-efficient signal routing
- LM low-profile stack height reduces total board assembly height to under 6 mm when mated
- Lead-free LC contact finish meets RoHS compliance for global market entry
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place at high production throughput
What is SFM-109-02-LM-D-LC-TR used for?
The SFM-109-02-LM-D-LC-TR serves compact board-to-board interconnect needs in wearable electronics, small form-factor industrial modules, and medical-device PCB stacks that require 18 signal lines within a footprint under 12 mm. Its low-profile mated stack height is critical in slim enclosures where total PCB assembly thickness must stay below 8 mm. The RoHS-compliant LC finish ensures the connector meets global environmental regulations in consumer and industrial markets.

Frequently Asked Questions
What position count and pitch characterize the SFM-109-02-LM-D-LC-TR?
The SFM-109-02-LM-D-LC-TR features 18 total positions in a 2-row by 9-position arrangement with a 0.050" (1.27 mm) pitch. This dual-row configuration covers a board footprint of approximately 11.4 mm in length, making it one of the more compact 18-circuit SMT socket options available in the SFM series.
For a wearable or medical device PCB stack, what mated stack height does the LM series achieve?
The LM designation targets a low mated stack height of approximately 4 mm to 5 mm above the PCB surface, enabling total dual-board assembly profiles under 8 mm including PCB thickness. This is ideal for slim wearable housings and medical implant modules where every 0.5 mm of height reduction matters for regulatory enclosure ratings.
How does a 18-position SFM connector compare to using two separate 9-position single-row connectors?
A single SFM-109-02 dual-row connector occupies roughly 50% less board width than two parallel single-row 9-position connectors at the same 1.27 mm pitch, saving approximately 3 mm to 4 mm of lateral PCB space. It also reduces placement operations from 2 to 1, cutting SMT cycle time by one pick-and-place step per board.
Can this connector be ordered in quantities suited to small prototype runs or is it designed for high-volume production?
The TR tape-and-reel format is optimized for high-volume SMT lines processing 1000 or more boards per run, but cut-tape options are often available for quantities as low as 10 to 50 pieces for prototype work. Lead times for standard tape-and-reel orders are typically 4 to 8 weeks, while stocked quantities at distribution can ship within 1 to 2 business days.
